"medium was a little small" - Review of MontBell America, Inc. Ultralight Thermawrap Jacket - Men's

I had to return it because it was too snug and felt restrictive. With about a 40 chest, 5'10" 165 lb., the medium was too small across the back and elbows. Great quality, a little on the crinkly side, as are most of these type fabrics, but very impressive for the money. Didn't want to send it back; tried it on again and again. Probably a Large would be nice. Looking at the Bozeman Mountain Works Cocoon offerings. Could this garment be superior in maintaining loft in the face of pressure from a shell?
